What our research says

Synthesia

The safe institutional choice for training video at scale — SCORM export and review workflows are what you are paying for, not the avatars themselves.

Pros

  • SCORM export and review workflows fit corporate training pipelines properly
  • A free Basic tier now exists, so the output can be tested before committing
  • Annual billing cuts the Starter seat from $29 to $18
  • Multi-language voiceover and dubbing are built in rather than bolted on

Cons

  • Paid credits are allocated per year, so a busy month can exhaust the budget
  • Avatar expressiveness trails HeyGen at comparable prices
  • Starter's roughly 120 minutes a year is thin for real course production
  • Unlimited minutes and the useful admin controls sit behind quote-only Enterprise

VideoGen

This is the assembly-line end of AI video: you are not directing shots, you are handing over a script and getting a watchable explainer or ad back with narration, footage and captions already in place. The timeline editor afterwards is what separates it from the one-click generators — you can fix the bits it got wrong instead of regenerating. Credits, not the subscription, are what actually limits you, and the API is a separate purchase at a big step up in price.

Pros

  • One pass produces script, voiceover, matched b-roll, subtitles and music together
  • Browser timeline editor lets you fix the output rather than only reroll it
  • Text-to-speech and translation cover 40+ languages
  • Pro includes commercial rights and API access; storage is a stated 50 GB rather than vague

Cons

  • Credit metering means the monthly price is a floor, not a ceiling — heavy generation costs more
  • B-roll selection is only as good as the library, and repeated stock clips are noticeable across a channel
  • The production API is a large separate line item ($360/month) rather than usage-priced
